Incorrect
current phasor
diagram
Phasor displays that show incorrect current probe connection can be corrected by
reconnecting the probe so that the arrow on the probe handle points toward the load.
The PowerVisa is able to display diagrams of the various wiring configurations to
assist users in the selection of circuit type appropriate for their application (see Chapter
5 Start Menu - Circuit Type Selection on page 5-11). The instrument compares the
detected voltages, currents, and phase sequence (if applicable) to the selected circuit
type. The PowerVisa issues a message if the specified circuit type and the actual
voltage/current connections match.
The next pages describe and illustrate the wiring configurations available for set up in
PowerVisa.
WARNING
Interconnect Jumpers bearing part number 114013-G1 supplied with the standard cable
set can be used to bond the same conductor points together. To reduce the risk of fire,
electric shock, or physical injury, it is strongly recommended that connections be made
with all circuits de-energized and current carrying conductors fused. If it is necessary to
make connections on energized circuits, these must be performed by Qualified
Personnel ONLY with Proper Personal Protective Equipment.
